[PATCH v1] drm/virtio: Set missing bo->attached flag

[Kasireddy, Vivek]

> Subject: [PATCH v1] drm/virtio: Set missing bo->attached flag
> 
> VirtIO-GPU driver now supports detachment of shmem BOs from host, but
> doing it only for imported dma-bufs. Mark all shmem BOs as attached, not
> just dma-bufs. This is a minor correction since detachment of a non-dmabuf
> BOs not supported today.
